Browsing through Dominaria's various Legendary creatures, a fella named Valduk, Keeper of the Flame caught my eye. I decided to stick to auras instead of going the equipment route as most may go. I also skipped the auras with powerful buffs to focus on the white auras that create creature when they enter the battlefield. Check it out:

3 Starfield Mystic
3 Sram, Senior Edificer
4 Champion of the Flame
2 Danitha Capashen, Paragon
3 Valduk, Keeper of the Flame
1 Odric, Lunarch Marshal
4 Cartouche of Solidarity
4 Temporal Isolation
3 Squire's Devotion
3 Sage's Reverie
3 Swords to Plowshares
4 Ancestral Blade
1 Tenza, Godo's Maul
22 Lands

There is a lack of one drops and there actually as many aura's as I'd like. However, it builds a pretty decent board once mana is available.
Couple things from the "reading iz tech department"; Valduk does not need to attack for his elemental creation to work. Also, Odric (a.k.a. Sean Connery, a.k.a. Zardoz) triggers on each players' attack phase.
Starfield Mystic is first on the chopping block. I'm trying no see if this works without Kor Spiritdancer 'cause that's too obvious. Probably also need to make room for an anthem of some kind, probably Force of Virtue.
